Every cam guy I talked to told me that they could grind a cam which would work better than the old MP .528 grind. I tried all the cams that people sent me and none of them actually worked better.

I'm pretty sure that if I picked up the phone today and called the cam grinders everyone would tell me again that yes they do have cams that work better than an old purple shaft. Question is do they, or are they kidding themselves?

Dwayne Porter is about the only guy who I would expect to deliver a cam that works better than the MP 528.

Most cam vendors do not have much experience with exhaust manifolds so they are really lost when it comes to designing a cam for that application. They'll tell you that they can grind a cam for you but when you dyno test it and tell them the numbers then they'll come back and say "oh yeah, looks like we need to adjust some things". That is okay if you're rich and have lots of time but most guys can't afford to do that much testing.
